Title: Heat insulation method of ladle
Inventor: SAKAI JISABUROU
IPC: B22D1/00
Filed: 1980-01-18
Abstract: PURPOSE: To form an expanded graphite layer by heat, insulate molten iron and improve workability by charging graphite powder which has been subjected to wet type oxidation treatment to the surface of the molten iron contained in a ladle.  
     CONSTITUTION: The graphite powder 3 which has beforehand been subjected to wet type oxidation treatment is charged through the opening of a ladle 2 containing molten iron 1. Then, the graphite powder 3 is rapidly heated and the interlayer compound of the inside decomposes to a gas which is released to the outside. At this time, the graphite powder 3 is expanded by the pressure of the releasing gas, whereby an expanded graphite layer 5 is formed on the molten iron surface 4, and the heat insulating effect more than equivalent to that in the conventional art is obtained with a small amount of the graphite powder 3.

Title: Method and equipment for identifying cancerous tissue and good or normal tissue
Inventor: ROBAATO AARU ARUFUANO
IPC: G01N21/64
Filed: 1991-01-18
Abstract: PURPOSE: To distinguish a cancerous tumor and tissue from a benign tumor and tissue or a normal tissue using natural fluorescence. CONSTITUTION: A tissue to be inspected is stimulated by a monochromatic light beam of 300nm. Intensity of natural fluorescence emitted from the tissue is measured at 340 and 440nm. Subsequently, the ratio between two intensities is calculated and used as a ground for deciding whether the tissue is cancerous or not through comparison with a benign or normal tissue. The invention is based on the finding that a natural fluorescent spectrum in the region of about 320-600nm represents a cancerous tissue when the tissue is stimulated with a monochromatic light of 300nm and it is significantly different from the natural fluorescent spectrum in case of a benign or normal tissue. This method is useful for in vivo and in vitro test of human and animal tissue.

Title: Wire dot printing head
Inventor: KIKUCHI KOU
IPC: B41J2/28
Filed: 1983-01-18
Abstract: PURPOSE:To perform the attraction and release of an armature in good efficiency, by a method wherein a permanent magnet for attracting the armature to hold the same to a standstill position and separately and independently provided to each printing wire. CONSTITUTION:When current supply to the coil 12 of a printing head is not performed, an armature 4 is attracted to the end surface of a core 11 by the magnetic force of a permanent magnet 9 and, under this state, the split pieces 5a of a lead spring 5 to which the armature 4 is secured are held to a state bent to the side of the core 11. When a current is supplied to the coil 12, a magnetic flux in the direction opposite the magnetic flux due to the permanent magnet 9 is generated in the gap between the armature 4 and the core 11 and the split pieces 5a of the lead spring 5 are released to forwardly return and protrude a printing wire 3 by the strain energy caused by the bending of said split pieces 5a. Because each permanent magnet 9 is made thin and provided in a separate and independent state, almost all of the magnetic fluxes due to the coil 12 pass the gap between the core 11 and the armature 4 acting on the release of the armature 4 and the release operation of the armature 4 can be performed in good efficiency while the magnetic interference between mutual wire drive means is reduced.
